==Key Stage 4==
===Meaning===
[[Fluid Pressure]] is the [[force]] per unit area on a surface due to [[particle]]s [[collide|colliding]] with that surface.

===About Fluid Pressure===
: The [[force]] responsible for [[pressure]] in a [[fluid]] is the [[weight]] of all the [[particle]]s above the [[object]].
: The [[pressure]] in a [[fluid]] decreases with height and increases with depth. The deeper into a [[fluid]] the greater the pressure.
: Since [[pressure]] increases with depth then the bottom of an [[object]] will experience more [[pressure]] than the top of the [[object]]. This causes a [[force]] called [[upthrust]].

===Equation===
Pressure = (Density of the Fluid) x (Gravitational Field Strength) x (Depth in the fluid)

<math> P = \rho g h</math>

Where:

<math> P</math> = [[Pressure]] at that depth.

<math> \rho</math> = [[Density]] of the [[fluid]]

<math> g </math> = [[Gravitational Field Strength]]

<math>h</math> = [[Depth]] in the [[fluid]]
